He said Jiwon follows his instincts and that he once called him hyung a bunch of times and clung to him.
In terms of his instincts, there's not much to dissect there. Its too broad a statement other than to say he doesn't overthink things and just does things without a filter.
As for the hyung part, you could say he becomes more affectionate, yes. And again, I acknowledge that he did kiss DG's neck.
But again, Jiwon's words and actions show that he's really just acting for his own self-pleasure. After DG said no, Jiwon immediately tried to sweet talk his way into having sex before putting it in anyway.
Nah, that's quite a weak point. And DG I hope you realize something about him. He's not in love with Alex, at least not yet. It has always been infatuation since the beginning. If he really did, he would have tried to understand why Alex is being such an asshole rather than keep whining about being ignored.
He's a freaking flat character I tell you. And until he started to see Jiwon as a flawed human, and not the ideal boyfriend he made up in his fantasies, he better stay away from Jiwon. Because we know in the end, both of them are gonna get hurt if they go further than this. Especially Jiwon.
Ch. 33 Spoilers
"Don't know if he just wants my body or this is his way of showing me how he feels..." He just wants your body.
Jiwon has been nothing but a self-serving jerk these entire 33 chapters. From the jerk comments in chapter one, to the disturbing jealousy scene (as a gay bottom, I was taken out of the reading because I understood just how much pain DG would realistically be in during that scene. There is no way that DG's ass wasn't ripped and he should have been much angrier), to this latest one (yeah, he kissed DG on the neck while drunk, but he also said after DG refused, "But I want to. Don't say no." before plugging it in anyway. This isn't about his love/lust for DG, its about getting off), Jiwon has no redeeming quality.
I want to continue reading to see when Jiwon acknowledges his interest in DG and hopefully has an arc of trying to makeup for being such a jerk (and if DG will stop being stupid and recognize that he doesn't deserve this treatment), but I can't pretend that any of this is a romance.
